Product Information



10X STIM is not for the faint hearted. At 24g per scoop 10X STIM is jampacked with ingredients that are backed by good science to help you get the most out of your workout. Most Brands will start by telling you what is included in their pre-workouts but we’re going to be different and start by telling you what’s NOT included in 10X STIM.


At 10X Athletic we don’t use:

Illegal & potentially unsafe stimulants. It’s just not how we roll. We pride ourselves on fuelling athletes of all abilities including Olympic and professional athletes. So, illegal or unsafe stimulants just don’t cut it with us.

Banned ingredients on WADA list. Enough said.

Proprietary blends. All our labels are fully transparent so you know exactly what you’re getting in every scoop. No nasties. No surprises.

Bad Science. Specifically we avoid using ingredients with poor science to back up their efficacy. Plenty of pre-workouts are packed full of cheap ingredients or ingredients with little or no science to back up their claims. We don’t do that.

Taurine. Did you know some brands add Taurine to their caffeinated pre-workouts and it actually makes their pre-workouts WORSE. Crazy, right? Did you know taurine and caffeine have opposite effects on your central nervous system? Caffeine is a powerful stimulant whereas taurine is an agonist for the inhibitory gamma aminobutyric acid (GABA) receptors. Did you know combining caffeine and taurine has NO tangible effect on your cardiorespiratory fitness, strength, power or cognitive ability? If anything it may have a detrimental effect on the pre-workout you are consuming. A 2017 study noted that combining taurine and caffeine actually INCREASED the feeling of FATIGUE. It Appears adding taurine to caffeinated pre-workouts is not a smart choice for the informed trainer who is looking for that pre-workout boost.


So what is included in 10X STIM:

8000mg Citrulline Malate 2:1 Looking for better performance, recovery, energy and more powerful pumps? Then citrulline is a ‘must’ in your pre-workout. Citrulline is a powerful (NO) Nitric Oxide boosting ingredient and has been found to be a more bioavailable and effective nutrient for boosting plasma levels of arginine than L-arginine supplementation alone. Before we go further let’s put the l-citrulline v citrulline malate debate to bed once and for all. There’s only one winner when you’re looking to maximize high intensity workouts and anaerobic performance. Unlike l-citrulline, studies have shown when subjects consumed 8000mg of citrulline malate they improved their performances during chest and leg resistance training exercises, increased repetitions & reduced their perceived exertion vs consuming a placebo. Additionally, subjects experienced as much as a 40% reduction in muscle soreness when compared to subjects that didn’t consume 8000mg of citrulline malate. Citrulline may also help your performance in the gym by reducing lactic acid accumulation in your muscles as it plays an important role in ammonia buffering.

3200mg Beta Alanine Supplementing with Beta Alanine has been shown to elevate carnosine levels in skeletal muscle tissue by up to 80%. This improves a muscles capacity to buffer hydrogen ions and offsets “the burn” sensation one experiences during intense exercise. Beta Alanine is an incredibly well researched ingredient and studies have shown 3200mg of Beta Alanine supplementation can help reduce fatigue and significantly increase endurance. So what does all of this mean? Simply speaking supplementing with Beta alanine can yield higher repetitions and superior performance in the gym. You might be wondering if the goal is to elevate carnosine why not supplement directly with carnosine instead? Studies have shown that beta alanine supplementation is more effective at increasing carnosine levels than supplementing with carnosine alone. Beta alanine is more bioavailable than carnosine so is more effective at elevating carnosine levels in your muscles. If you’re not used to supplementing with beta alanine please be aware of the ‘tingling’ (paraesthesia) sensation. Start with a lower dose and build up your tolerance.

3000mg Creatine Monohydrate Quite possibly the most thoroughly researched and effective ingredient in sports nutrition. Creatine monohydrate is not only heavily researched but it also has a ton of evidence to support its efficacy. Creatine is an osmolyte that improves cellular hydration and ATP regeneration in your muscle cells. During exercise ATP is broken down to produce energy. Creatine supplementation increases phosphocreatine stores which means there is more ATP energy to fuel muscles during high-intensity exercise. As well as helping your muscle cells produce more energy, studies have shown supplementing with creatine monohydrate may lead to an increase in strength, muscle mass, muscle endurance and help aid recovery amongst other benefits. Creatine monohydrate is the gold standard and is a must for any serious trainer. Creatine, like Beta Alaine is a saturation product and it doesn’t require a loading phase. However it is not uncommon for trainers to consume 3-5g of creatine pre and post workout.

Caffeine Anhydrous 450mg Simply speaking caffeine is the king of (safe) stimulants and is the main energy boosting ingredient in most pre-workoouts. Research into the physiological effects of caffeine on physical and mental performance are very extensive. Caffeine levels in your body peak approx. 45-60 minutes after ingestion and can remain high for 3-4 hours before they begin to drop so it’s not advisable to take caffeinated pre-workouts late in the day. Caffeine antagonizes adenosine and GABA receptors (neurotransmitters that induce the feeling of tiredness and lethargy). By preventing the binding of these neurotransmitters to their partner receptors caffeine has been shown to increase mental energy, focus and motivation as well as enhancing the feeling of alertness and improve reaction times. A recent study found that 4.45mg/kg or approx. 400mg of caffeine increased endurance in athletes and help burn more calories. Studies have shown combining taurine with caffeine can have an adverse effect on the cardiovascular system and can increase the feeling of fatigue. Simply put, avoid combining caffeine and taurine in your pre-workouts.

400mg Peak ATP Peak ATP is a patented form of Adenosine 5’-Triphosphate (ATP) Disodium. Peak ATP is identical in structure to the ATP produced and used in the human body. All living cells use ATP for energy. During exercise the demand for ATP increases massively and the rate of ATP turnover can limit high-intensity performance. In clinical studies Peak ATP has been shown to boost muscular power output, improve blood flow, increase number of repetitions performed, increase lean body mass and reduce fatigue versus placebo. Based on research the recommended dose of Peak ATP is 400mg, the exact amount in your 10X pre-workout. Ideally, it should be taken (in your pre-workout) 30-60 mins prior to exercise.

2500mg Betaine Anhydrous Betaine is a heavily researched, safe and highly effective performance boosting supplement. Betaine is a natural osmolyte like creatine and promotes cell hydration. It also synergises with creatine to enhance the biosynthesis of creatine in the human body. As an osmolyte betaine enhances intracellular water which encourages muscle volumizing and muscle swelling. Research has shown that muscle swelling stimulates muscle protein synthesis and decreases protein breakdown, this ultimately leads to increased muscle size. Studies have shown 2500mg of Betaine supplementation may significantly increase anaerobic power, muscle protein synthesis and lean mass gains in athletes.

1000mg L-Tyrosine Research has shown supplementing with tyrosine may increase levels of the neurotransmitters adrenaline, norepinephrine and dopamine. These are important brain chemicals which affect alertness, mood and your stress response. L-tyrosine is a dopamine precursor, a chemical that regulates the ‘reward and pleasure’ centres in your brain. Since reduced levels of dopamine decrease motivation and performance, increasing dopamine levels may have the effect of boosting brain function, mood and performance under certain conditions.

1000mg Beet Root Extract Beetroot extract is another powerful (NO) Nitric Oxide boosting ingredient. The nitrates found in beetroot juice and supplements have been shown to increase Nitric Oxide secretion. Human studies suggest that boosting NO may improve muscle pumps and performance in high intensity interval training and prolonged aerobic training.

700mg Electrolytes Electrolytes are minerals that get electrically charged when dissolved in liquid and are essential for many important body functions. Like many other compounds in the human body, electrolytes need to stay within a certain range for proper health and function. During intense exercise the body loses electrolytes and water through sweating. Depletion of electrolytes can lead to performance decline, fatigue, cramping and increase the risk of injury. So we added Potassium, Magnesium and Sodium to our pre-workout to replenish these vital minerals. These are 3 of the most common electrolytes that help support muscle contractions, nerve impulse conduction, regulate heart rate and fluid balance in the body amongst many other benefits. Research has shown supplementing with potassium and magnesium promotes vasodilation by increasing (NO) Nitric Oxide and prostacyclin leading to improved blood flow and lower blood pressure.

B Vitamins inc 800ug Folic Acid Folic Acid is a highly bioavailable form of vitamin B9. It plays an important support role in the production of dopamine and nitric oxide. B3 (niacin) plays an important role in energy metabolism and cell health. B6 (pyridoxal 5’-phosphate) may improve mood, reduce symptoms of depression & improve brain health. Vitamin B12 (methylcobalatim) is an essential vitamin your body can’t produce. Supplementing with B12 may help support the normal function of nerve cells, energy production and even help to minimize risk for cardiovascular disease. B12 also serves as an important cofactor in the production of dopamine.

20mg Bioperine and AstraGin Bioperine is a patented black pepper fruit extract used in pre-workout supplements to enhance nutrient uptake and absorption through its active component piperine. Piperine is also a high-level anti-inflammatory, anti-oxidant and a dopamine maximiser in the body (by stimulating the TRPV receptor in the brain). AstraGin is a patented, 100% plant-derived compound that also increases the absorption of many vital nutrients. Bioperine and AstraGin work synergistically to increase nutrient absorption and nutrient uptake, this can help you get more from your pre-workout.
